基本思路很简单：
先得到鼠标点击的位置并记录，鼠标移动时得到移动后的位置计算出差值，然后平移。
代码：
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows;
using System.Windows.Controls;
using System.Windows.Data;
using System.Windows.Documents;
using System.Windows.Input;
using System.Windows.Media;
using System.Windows.Media.Imaging;
using System.Windows.Navigation;
using System.Windows.Shapes;
namespace DragWindowTest
{
/// <summary>
/// MainWindow.xaml 的交互逻辑
/// </summary>
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
}
private static bool IsDrag = false;
private double enterX;
private double enterY;
private void Window_MouseLeftButtonDown(object sender, MouseButtonEventArgs e)
{
IsDrag = true;
enterX = e.GetPosition(this).X;
enterY = e.GetPosition(this).Y;
}
private void Window_MouseLeftButtonUp(object sender, MouseButtonEventArgs e)
{
IsDrag = false;
enterX = 0;
enterY = 0;
}
private void Window_MouseMove(object sender, MouseEventArgs e)
{
if (IsDrag)
{
this.Left += e.GetPosition(this).X - enterX;
this.Top += e.GetPosition(this).Y - enterY;
}
}
}
}
